These fabrics
are comfortable to wear, easy to care for, do not lose their original
shape for a long time — they do not shrink and do not stretch [8].
III EXPERIMENTAL RESULTS
Experimental studies were conducted at the Tashkent Institute of textile and
light industry in order to obtain a fabric that meets the requirements for sports and
medical and preventive products.
Elastic yarn in several additions with the same tension was wound on a cane
machine of the Italian company "FADIS". Twisting is given on a twisting machine
of the company " Saurer‖, VTS-08-0-S Czech Republic.

Creating fabrics for compression products with high compression effect and
strength requires high quality yarn. To develop a pilot mixed fabric, 2 versions of
yarn were prepared using the following components:
1 st option-95.0% polyester fiber with a linear density of 17.0 Tex x3 and
5.0% lycra 4.5 Tex x2, the number of twists 150 kr/m;

2 nd option-92.0% polyester fiber with a linear density of 17.0 Tex x3 and
8.0% lycra 4.5 Tex X3, the number of twists 150 kr/m;
In the 1 st option, an elastic yarn of linear density 69.6 Tex is used as a basis
in three additions of yarn of linear density 20.7 Tex x3.
In the 2
nd option, 58.0 Tex yarn was produced by adding three polyester
yarns with a linear density of 17.0 Tex x3 with three threads of lycra with a linear
density of 4.5 Tex.
As can be seen from table 1, the average breaking load of the first variant of
the sample of elastic yarn is 1464.4 cN, for the second variant 1699.2 cN. Figure 2
shows a graph of elongation versus sample deformation.
The quality of the experimental yarn was evaluated
on the basis of physical
and mechanical parameters of the yarn (table.1).
